Increase day function?

[Dumpie]

Hi all,

I'm busy with making a reservation system.
People can select the start date and the interval (everday, every week, every month) and the end date.
But the problem is how to get the date 2 weeks after eachother, etc?

Also, I can't run a while loop (while(start_date < end_date) becouse php doesn't see these things as dates.

Any1 can help me?

Many, many thanx in advance!

Check function mktime() especially its examples.

You'll be fidling with mktime which turns date into timestamp and thats what you want to do when using that start_date and end_date
